Watermelon Feta Salad

This recipe, adapted from one on the website of the National Watermelon Promotion Board, was a real surprise when I first tried it. I had no idea how delicious watermelon and feta cheese could be together. And with red onion, chopped romaine and a fresh basil vinaigrette, the salad is crunchy, juicy, sweet, salty and zingy all at the same time.
